To H'mm if 1174/11/ enne/)171;

Be it known that LYVILLIAM C. BUnGt'iua i the molds after the molds aredischarged` from a brick-machine and to simplifv and 2o improve theeonstruction olY this elass of apparatus.

ln the accompanying drawings,whieh illust trate an application of myinvention, Figure l is a front elevational view of a machine eonz5structed m accordance with my invention;

Fig, 2, a sid e elevational view, showing a por 1 tion of al)rick-mat'hine and my attachment; 1

Fig. 2%, a detail view of mold-engaging means and showing the positionof said means dis- 3o engaged from the mold: Fig. i, a detail viewshowing manner of supporting the rod on which the knife is carried, andFig. 5 a detail view of knife and weight.

leferring to the drawings, l show a portion of a brick-maehine having awheel 2. As illustrated, the wheel 2 is emplo ved for actuating tlieparts: but other suitable means ma v be einploved in plaee of the wheel.

represents a table extending outwardly 4o from the brick-imichine uponwhich the molds l are delivered in the usual manner. Located on bothsides of the table are two posts or uprights 5. crossbar t3. having itsbearings in blocks 7. -t5 Passing through and extending downwardlv frombar ti l emplojv two rods 8, having forked lower ends t). These rods Sare ver ticalfv adjustal'ile in cross-bar 6 by means rlhese postssupport a of the nuts l0. laieated within the forked portions t) of eachrod S are movable slide- 5o bearings ll. Bearings il support a rod 1.2,on which a knife or blade 12% is mounted. lYeighted members '1-t arealso carried on rod v l2. The forked ends of rods b' are joined bv abolt l5, upon which the bearings ll rest 55 when the v reach the. limitof their downward movement within the forked ends.

L\ttaehed to the posts 5 and arranged in the patti of travel of theweights 14 are two angular plates lttt. The Vfunetion of these 6o platesis to throw the weights in such a manner as to bring the knife. 133 intooperative positions.

As illustrated, eross-bar t5 is eomieeted up with driving-wlieel 2 bymeans of angle-le- 65 vers 16 and i7, and 1S is another level' moved bvbar t3 for the purpose of actuating the mechanism designed to hold themold in position against the action of the knife during its` forwardmovement. This mechanism in 7o addition to the lever 1.8 comprises a rodlt), contact-lingers 2t), mounted on rod 1t), arms 2l, a bent rod 22,and a weight 23.

The position of the parts as shown by full l lines, Fie. 2, is such asthey assume in start- 75 ing the torward stroke of the knife. A conttinued movement of cross-bar t, actuated bv the wheel and the levers loand l7,earries the l knife into the position shown b v dotted lines.

During the baekward swing of the knife the 8o weights it strike againstthe plates it, therel by causing the rod l2 to turn and bring the knifeinto an operative position for the ret turn or backward cut. lt willthus be seen that the knife cuts the surplus clay in two di- S5rections, preferably starting to out about inidwa)V of the mold both onthe forward i and baekward stroke. .hugs 2-.t are provided to raise themold being operated upon above the following knife striking the moldfollowing before said i mold is in proper position. Upon the return lstroke of the knife weight 22% is raised, as well i as arms 2l, thuscausing the lingers to drei l below the finished mold. On the sueeeedint forward stroke of the knife the weight ar mold in order to prevent the9c arms 21 descend and cause the fingers to return to their formerposition ready to prevent a forward movement of the mold.

What I claim is` l. In an attachment for brick-machines, thecombination, with a mold, of means for removing the surplus materialfrom the mold comprising a movable blade or knife arranged to be movedover the mold in two directions, means for supporting and moving theblade or knife,.means for bringing the blade or knife into operativepositions comprising a member carried with the blade or knife and a partlocated in the path of travel of the member, and means for maintainingthe mold in position during the cutting operations, substantially as setforth.

2. In an attachment for brick-machines, the combination, with a tableand a mold, of a movable knife arranged to travel over the mold in twodirections for the purpose of removing the surplus material from themold, means for supporting and actuating the knife, and means forturning the knife so as to bring the knife into operative positionscomprising a weighted member carried with the knife and a plate locatedin the path of travel of the member, substantially as set forth.

3. In an attachment for brick-machines, the combination, with a mold anda support therefor, of an oscillating knife arranged to be moved overthe mold, a cross-piece, forked hangers connected with the cross-piece,a rod on which the knife is mounted, movable slide-bearings for said rodlocated in the forked hangers and arranged to move vertically therein asthe knife is oscillated, means for turning the knife into operativepositions, and means for moving the cross-piece, substantially as setforth.

4. In an attachment for brick-machines, the combination, with a mold anda support therefor, of an oscillating knife arranged to be moved overthe mold, a cross-piece, hangers connected with the cross-piece, a rodon which the knife is mounted, a weighted member carried with the rod,movable bearings for the rod located in the hangers,a plate arranged inthe path of travel of the weighted member, and means for moving thecrosspiece, substantially as set forth.

5. In an attachment for brick-machines, the combination with a mold, ofan oscillating knife arranged to be moved over the mold,

means to maintain the mold in the desired position during cuttingoperation, and means for actuating the knife and the mold-retainingmeans, substantially` as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
